BACKGROUND OF THE PRESENT INVENTION Field of Invention

The present invention relates a beverage container, and moreparticularly to a beverage container comprising a rotatable sealingarrangement, in which a cover assembly and a sealing piece provides adouble sealing effect to an access opening of a lid body so as toprevent liquid from spilling out of the beverage container even when itis flipped side way or turned upside down.

Description of Related Arts

A conventional container, such as a beverage container for containingwater, usually comprises a container body and a lid detachably attachedon the container body. The container body has a container cavity forstoring a predetermined amount of fluid, such as water. The lid usuallycomprises a lid body having a drinking hole communicating with thecontainer cavity, and a sealing handle movably mounted on the lid bodyfor selectively opening or closing the drinking hole.

Conventionally, the sealing handle may be coupled to the lid body insuch a manner that the sealing handle can rotate with respect to the lidbody. Through rotational movement of the sealing handle, the sealinghandle may be selectively rotate to open and block the drinking hole.

A major disadvantage of the conventional beverage container such as theone mentioned above is that there is no locking mechanism to restrictthe rotational movement of the sealing handle. For those beveragecontainers which utilize similar structures, the sealing handle istightly coupled to the lid body so that although the sealing handle mayrotate with respect to the lid body, it is very hard for a user torotate the sealing handle for opening and closing the drinking hole.This disadvantage presents great inconvenience to users especially whenthe beverage container is being used in outdoor environment or the usersare very young (such as kids) when he or she does not have adequatepower to turn the sealing handle.

Moreover, most conventional beverage containers having the sealinghandle as mentioned above does not have adequate sealing so that whenthe beverage container is flipped side way or turned upside down, liquidin the beverage containers may spill out of the container.

Therefore, there is a need to develop a beverage container having arotatable sealing handle which is easy to be rotated, which can belocked and unlocked with ease, and which has a superior sealingperformance.

In other words, theupper tubular portion 212 constitutes a circumferential boundary of theupper cavity 2121, and the lower tubular portion 213 constitute acircumferential boundary of the lower cavity 2131.

The through central opening 23 may be surrounded by a sidewall 25 of thelid body 21. The lid body 21 may further has a plurality of securinggrooves 214 indently formed on the sidewall 25. In this preferredembodiment of the present invention, the through central opening 23 mayhave a circular cross section and the securing grooves 214 may bepositioned on the sidewall 25 in such a manner that the securing grooves214 may face each other. That is, they may be configured to be oppositeto each other.

Since each of the securing grooves 214 is indently formed on thesidewall 25, therefore, each of the securing grooves 214 may form twobiasing shoulders 2141 with the sidewall 25 at two ends of thatcorresponding securing groove 214.

Moreover, the lid body 21 may further comprise a plurality of protectiveshields 26 downwardly extended from a bottom surface 221 of the toppanel 22 in the lower cavity 2131, wherein the main shaft 33 and thecoupler ring 35 may be received in the space surrounded by theprotective shields 26. As shown in FIG. 3 and FIG. 11 of the drawings,each of the protective shields 26 may be configured as having apanel-like structure having a curved contour, wherein a radius ofcurvature may correspond to that of the through central opening 23.

The lid body 21 may further have a venting hole 27 formed on the toppanel 22 at a position opposite to the access opening 24 forfacilitating easy flowing of liquid through the access opening 24 whenthe cover assembly 31 is in the opened position.

The lid body 21 may further have a plurality of first engaging threads215 formed on an external surface of the lower tubular portion 213 whilethe container body 11 may have a plurality of second engaging threads 15formed on an inner surface surrounding the container cavity 11 near thetop opening 12, wherein the first engaging threads 215 and the secondengaging threads 15 may be positioned to correspond to each other sothat the lid body 21 may engage with the container body 11 throughdetachable engagement between the first engaging threads 215 and thesecond engaging threads 15. An external diameter of the enlarged rimportion 211 may be larger than an internal diameter of the containercavity 11 so that when the lid body 21 is detachably attached on thecontainer body 10, the top opening 12 may be fully covered by the lidbody 21.

Referring to FIG. 4 and FIG. 9 of the drawings, the main shaft 33 of thecover assembly 31 may have an upper shaft portion 331, a lower shaftportion 332, and a middle shaft portion 333 extending between the uppershaft portion 331 and the lower shaft portion 332. The main shaft 33 asa whole may be arranged to be mounted in the lower cavity 2131 of thelower tubular portion 213 by penetrating through the through centralopening 23.

The main shaft 33 may further comprise a plurality of (but at least one)guiding ridges 334 extending along the middle shaft portion 333 along alongitudinal direction thereof in a spiral configuration. Each of theguiding ridges 334 may have a locking indention 3341 formed thereon. Themiddle shaft portion 333 of the main shaft 33 may be configured to havean elongated and tubular structure.

According to the preferred embodiment of the present invention, each ofthe upper shaft portion 331, the lower shaft portion 332 and the middleshaft portion 333 may have a circular cross sectional shape, wherein adiameter of the upper shaft portion 331 of the main shaft 33 may belarger than that of the middle shaft portion 333 while a vertical heightof the upper shaft portion 331 may be smaller than that of the middleshaft portion 333.

On the other hand, the lower shaft portion 332 may be divided into acontracted section 3321 and a lower end section 3322, wherein a diameterof the contracted section 3321 may be smaller than that of the lower endsection 3322 to form a circumferential slot 3323 at the lower shaftportion 332 due to change in diameter between the contracted section3321 and the lower end section 3322.

The main shaft 33 may further comprise a plurality of securingprotrusions 335 extended from the upper shaft portion 331 along atransverse direction of the main shaft 33. The securing protrusions 335may be slidably received in the securing grooves 214 respectively. Thesecuring protrusions 335 may also be connected to the first sealingcover 34 in such a manner that when the first sealing cover 34 is drivento rotate, the securing protrusions 335 may also be driven to rotatealong the securing grooves 214 respectively. When the securingprotrusion 335 hit the corresponding biasing shoulder 2141, furtherrotation of the first securing cover 34 with respect to the lid body 21may be stopped. Hence, a length of the securing grooves 214 dictate theextent to which the first securing cover 34 may be rotated.

The first sealing cover 34 may transversely extend from the upper shaftportion 331 of the main shaft 33 and may be positioned on the top panel22 of the lid body 21. In the preferred embodiment of the presentinvention, the first sealing cover 34 may be positioned on a top surface222 of the top panel 22.

Referring to FIG. 5 to FIG. 6 of the drawings, the first sealing cover34 may have an elongated portion 341 and an engagement portion 342constituted by a first wall 3421, a second wall 3422 and a third wall3423 extending between the first wall 3421 and the second wall 3422. Theengagement portion 342 may define an engagement slot 3424 as a spacesurrounded by the first wall 3421, the second wall 3422 and the thirdwall 3423. The engagement slot 3424 may engage with the upper tubularportion 212 of the lid body 21 such that a circumferential tubular wall2122 of the upper tubular portion 212 may be received in the engagementslot 3424 in a slidably movable manner. A lock 50 may be provided toselectively lock the engagement portion 342 to the upper tubular portion212.

In this preferred embodiment of the present invention, the first wall3421 may upwardly extend from one end of the elongated portion 341,while the second wall 3423 may transversely or sidewardly extend fromthe first wall 3421 to ride over the circumferential tubular wall 2122of the upper tubular portion 212, while the third wall 343 verticallyextend from the second wall 3423. This configuration may be shown inFIG. 1 and FIG. 2 of the drawings.

Thus, the elongated portion 341 may be arranged to cover the accessopening 24 and the venting hole 27 when the cover assembly 31 is in theclosed position. On the other hand, the elongated portion 341 may berotated to expose the access opening 24 and the venting hole 27 toambient environment when the cover assembly 31 is in the openedposition. From the above descriptions, one skilled in the art mayappreciate that the first sealing cover 34 may seal or cover the accessopening 24 and the venting hole 27 from a top side of the top panel 22(i.e. from a top side of the access opening 24 and the venting hole 27).

The sealing piece 32 may be mounted underneath the top panel 22 toprovide sealing to the container cavity 11 from underneath the top panel22. The sealing piece 32 may further comprise a vent cover 37 outwardlyextended from the coupler ring 35 in a direction opposite to the secondsealing cover 36. In this preferred embodiment of the present invention,the second sealing cover 36, the coupler ring 35 and the vent cover 37may form an integral structure.

The sealing piece 32 may further comprise a plurality of travelingmembers 38 inwardly protruded from the boundary wall 352 of the couplerring 35 and slidably engaged with the guiding ridge 334. The main shaft33 of the rotatable sealing arrangement 30 may be arranged to penetratethe through hole 351 of the coupler ring 35 with the traveling members38 slidably engaging with the corresponding guiding ridges 334respectively. When the main shaft 33 is driven to rotate, the guidingridges 334 are also driven to rotate, which force the traveling members38 to travel along the corresponding guiding ridges 334 respectively.Note that the spiral orientation of the guiding ridges 334 is such thatwhen cover assembly 31 is driven to rotate from the closed position tothe opened position, the main shaft 33 may be driven to rotate such thatthe traveling members 38 may travel downwardly with respect to the mainshaft 33 along the corresponding guiding ridges 334. As such, thesealing piece 32 may also travel downwardly with respect to the mainshaft 33 and away from the top panel 22.

The sealing piece 32 may further comprises a first blocker member 321and a second blocker member 322 extended from the second sealing cover36 and the vent cover 37 respectively. The first blocker member 321 andthe second blocker member 322 may be configured as protrusionsrespectively which may upwardly extend from the second sealing cover 36and the vent cover 37 toward the access opening 24 and the venting hole27 respectively for enhancing the sealing performance of the sealingpiece 32.

As shown in FIG. 3 of the drawings, as an exemplary configuration, thevent cover 37 may have an elongated structure extending from the couplerring 35, while a width of the second sealing cover 36 may graduallyincrease from the coupler ring 35 toward a far end thereof.

The rotatable sealing arrangement 30 may further comprise a resilientelement 39 and an end stopper 391 mounted on the main shaft 33 forproviding an upward urging force toward the coupler ring 35 so as topush the coupler ring 35 toward the top panel 22. Specifically, theresilient element 39 may be configured as a compression spring and maybe mounted on the main shaft 33. On the other hand, the coupler ring 35may further have a circumferential protrusion 353 circumferentially andinwardly extended from the boundary sidewall 352 so as to form a biasingplatform 354 as a bottom surface of the circumferential protrusion 353.The resilient element 39 may bias against the biasing platform 353 whenit is mounted on the main shaft 33. Thus, the sealing piece 32 may besubject to an upward urging force so as to seal the access opening 24and the venting hole 27 from underneath the top panel 22.

On the other hand, the end stopper 391 may be mounted on the lower shaftportion 332 of the main shaft 33. As shown in FIG. 5 of the drawings,the end stopper 391 may comprise a stopper body 392 having an upper wall3921, a lower wall 3922 and a peripheral wall 3923 extended between theupper wall 3921 and the lower wall 3922. The stopper body 392 may beconfigured to be a hollow structure so as to define a mounting cavity3924 between the upper wall 3921, the lower wall 3922 and the peripheralwall 3923. In this preferred embodiment, each of the upper wall 3921 andthe lower wall 3922 may have a substantially circular cross section whenviewed from the top.

Moreover, the upper wall 3921 may have a stopper slot 393 formed on theupper wall 3921. The stopper slot 393 may have an elongated structureand extend from a peripheral edge of the upper wall 3921 toward a centerthereof. As a result, the upper wall 3921 may have a mounting opening3925 formed as the opening of the stopper slot 393. As will be describedbelow, the end stopper 391 may be arranged to couple to the main shaft33. Thus, a width of the stopper slot 393 may be larger than a diameterof the contracted section 3321 of the lower shaft portion 332 butsmaller than a diameter of the lower end section 3322.

As shown in FIG. 9 of the drawings, the end stopper 391 may be coupledto the lower shaft portion 332 of the main shaft 33 in such a mannerthat the contracted section 3321 of the lower shaft portion 332 may beslidably inserted into the stopper slot 393. Once the contracted section3321 of the lower shaft portion 332 has been inserted into the stopperslot 393, an upward movement of the main shaft 33 will be limited by theupper wall 3921 of the end stopper 391. At the same time, the lower endsection 3322 may be received in the mounting cavity 3924 in which aheight of the lower end section 3322 is substantially identical to avertical height of the mounting cavity 3924. Therefore, a downwardvertical movement of the main shaft 33 may also be limited by the lowerwall 3922 of the end stopper 391.

In other words, when the end stopper 391 is coupled to the lower shaftportion 332, a vertical movement of the main shaft 33 and the firstsealing cover 34 may be securely retained and a relative verticalmovement between the main shaft 33, the first sealing cover 34 and thelid body 21 may also be limited. The resilient element 39 may bepositioned between the upper wall 3921 and the coupler ring 35, in sucha manner that when the end stopper 391 is coupled to the main shaft 33,the resilient element 39 is arranged to exert an upward urging forcetoward the coupler ring 35 of the sealing piece 32. For example, theresilient element 39 may be a compression spring such that when the endstopper 391 is coupled to the main shaft 33, the resilient element 39 isslightly compressed and exert an upward urging force toward the sealingpiece 32 so as to force the sealing piece 32 to seal the access opening24 and the venting hole 27 from underneath the top panel 22.

The operation of the present invention may be described follows: whenthe cover assembly 31 is in the locked position, the first sealing cover34 may be rotated such that the elongated portion 341 completely coverthe access opening 24 and the venting hole 27 from the top of the toppanel 22. At the same time, the sealing piece 32 may be pushed by theresilient element 39 so that the second sealing cover 36 and the ventcover 37 may be pushed to cover the access opening 24 and the ventinghole 27 from underneath the top panel 22. This creates a double sealingeffect (one from above the top panel 22 and one from underneath the toppanel 22) to seal the access opening 24 and the venting hole 27. Theresult is that when the when the cover assembly 31 is in the lockedposition, liquid in the container cavity 11 is prevented from spillingout therefrom through the access opening 24 and the venting hole 27,even when the beverage container is flipped sideway or turned upsidedown.

When a user wishes to drink the liquid stored in the container cavity11, he or she may rotate the first sealing cover 34 and the securingprotrusions 335 may also be driven to rotate along the securing grooves214 respectively. At the same time, the main shaft 33 may also berotated and the traveling members 38 may travel along the guiding ridge334 and cause the entire sealing piece 32 to move downwardly along themain shaft 33 so as to remove the blocking or sealing from underneaththe access opening 24 and the venting hole 27. The traveling members 38may continue traveling along the guiding ridges 334 until the travelingmembers 38 reach the locking indentions 3341 respectively. The lockingindentions 3341 provide a weak retention force keep the travelingmembers 38 therein. The lengths of the securing grooves 214 may also bedesigned so that when the securing protrusions 335 reach the biasingshoulders 2141 respectively, the traveling members 38 are simultaneouslyreceived in the locking indentions 3341 respectively. At this time, theresilient element 39 as the compression spring is compressed. This hasthe effect of temporarily holding the first sealing cover 34 in positionwhile the access opening 24 and the venting hole 27 are opened so that auser may drink the liquid stored in the container cavity 11 with easeand without needing to manually hole or retain the first sealing cover34.

When the user finishes drinking the liquid, he or she may simply exert aslight force to the first sealing cover 34 in the direction which tendto close the access opening 24 and the venting hole 27. This slightforce disengages the traveling members 38 from the locking indentions3341. The upward pushing force exerted by the retention element 39 maycause the traveling members 38 to go back up along the guiding ridges334 and this cause the entire sealing piece 32 to move upwardly alongthe main shaft 33 and back to its original position. At the same time,since the traveling members 38 are driven to move back up along thespiral guiding ridges 334, the first sealing cover 34 may be forced torotate to move back to the original position so as to close the accessopening 24 and the venting hole 27. At this time, the cover assembly 31may be restored to the closed position.

One skilled in the art may appreciate that when the user has exerted theslight force to disengage the traveling members 38 from the lockingindentions 3341, the cover assembly 31 (including the first sealingcover 34 and the sealing piece 32) will automatically restore to theclosed position due to the effect of the retention element 39.
